Other ways to prevent haemolysis include prescreening patients for active haemolysis, modifying the dose/rate regimen (for example, using the lowest effective dose, infusing slowly), pretreatment with steroids to reduce macrophage activation and increased AZD1208 order monitoring post-infusion. While IgG is well tolerated by the vast majority of patients, thromboembolic and haemolytic events can occur in some, and can be exacerbated by high doses and rapidity of infusion. Thrombotic events occur mainly in elderly patients with pre-existing

risk factors receiving i.v. infusions, and have been associated with activated clotting factors existing as contaminants in some IgG products. Trace haemolysis is fairly common but is rarely severe, and can usually be attributed to anti-A and/or anti-B isohaemagglutinins in the IgG product. Research is under way to identify risk factors for

these adverse events, and also ways to remove their causative components from the IgG product. F. A. B. would like to thank Meridian HealthComms Ltd for providing medical writing services. F. A.

It has a controversial pathogenesis and has been implicated as a potential cause of irritable bowel syndrome. Our previous studies identified pigs as potential animal models for blastocystosis by demonstrating that they were likely natural hosts of Blastocystis and can harbour subtypes (ST) in common with humans. Furthermore, our finding of a lack of intestinal histopathology associated with

Blastocystis infection in pigs is also a consistent finding in examined infected humans. In this study, we aimed to identify and characterize the Blastocystis-specific mucosal IgA response in pigs by immunoblotting, using pig faecal antibodies and Blastocystis antigen. Phosphoglycerate kinase Faeces from 233 pigs representing three age groups (sows/boars, growers/weaners and piglets) and including five dexamethasone-immunosuppressed research pigs were tested. The majority (81·5%) of the pigs had faecal IgA reactivity against Blastocystis proteins of molecular weights of 17·5–120 kDa. Reactivity to a >250 kDa protein was found in 18·5% of pigs. Notably, immunosuppressed pigs and piglets were statistically more likely to have reactivity to this protein compared to growers/weaners and sows/boars, respectively. These results corroborate other findings suggesting that compromised immunity may predispose to blastocystosis and support our contention that pigs are potentially good models for pathogenesis studies.
